Calisthenics are also great. Most are surprised by the physique attainable. Unfortunately the US is awful about free outdoor fitness equipment--I wish that changed. In many countries you can easily find outdoor gyms, but in the US a playground or even a combination of park benches, a tree, and some railings will do. For the record 99% of the time I've only received positive attention from this, but sometimes there are haters (usually either homeless people or overweight women in SUVs--just being honest). The only weights I might buy are a couple of 10 litre water containers -- usually a few bucks at a supermarket -- for shoulder exercises.
